Noble metal catalysts refer to a class of catalysts that are composed of noble metals, which include platinum (Pt), palladium (Pd), rhodium (Rh), ruthenium (Ru), iridium (Ir), and gold (Au). These metals are categorized as “noble” due to their high resistance to oxidation, corrosion, and chemical reactions under normal conditions.

These metals exhibit unique catalytic properties, leading to diverse catalyst types and applications:

1. Platinum (Pt) Catalysts:

   • Pt catalysts are widely utilized in various reactions, including hydrogenation, dehydrogenation, oxidation, and fuel cell applications. They are particularly valuable in automotive catalytic converters for converting harmful pollutants in exhaust gases into less harmful emissions.

2. Palladium (Pd) Catalysts:

   • Pd catalysts are extensively used in hydrogenation reactions, such as the hydrogenation of alkenes, nitro compounds, and in the synthesis of pharmaceuticals and fine chemicals. They are also employed in catalytic converters and pollution control systems.

3. Rhodium (Rh) Catalysts:

   • Rh-based catalysts find applications in various oxidation reactions, including catalytic converters in automobiles for reducing nitrogen oxides (NOx). They are also used in industrial processes for manufacturing acids, pharmaceuticals, and chemicals.

4. Ruthenium (Ru) Catalysts:

   • Ru catalysts are employed in a range of catalytic processes, including ammonia synthesis, olefin metathesis, hydrogenation, and organic transformations in the chemical and pharmaceutical industries.

5. Iridium (Ir) Catalysts:

   • Ir catalysts are utilized in hydrogenation, oxidation, and organic synthesis reactions, especially in niche applications requiring high stability and selectivity, such as in fuel cell technology and fine chemical production.

6. Gold (Au) Catalysts:

   • Au catalysts exhibit unique catalytic properties, particularly in oxidation and hydrogenation reactions. They find applications in specialty chemical synthesis, pharmaceuticals, and green chemistry processes.

These noble metal catalysts can be used in different forms, including supported catalysts (where the noble metal is supported on a substrate such as carbon, alumina, or zeolites), nanoparticles, alloys, and complex structures tailored for specific reactions and industries.
